I am trying to call an XML (non-SOAP) web service with C#.
I was provided with a request schema by our web services team, and I
generated a CLR class for it using XSD.exe.
When I instantiate this schema class and try to set a property on it,
however, I get the following error:

 Object reference not set to an instance of an object.

This is essentially the code that's causing the error:

MyRequestSchema request = new MyRequestSchema();
MyRequestSchema.FirstName = "Jonathan";

Any idea what I'm doing wrong?

Thanks,
Jonathan
